I'll put aside two facts, (Armor 5 is going to be hard to kill & my Laser units have done phenominally well for me), if the same formula is applied to the stats from the Herman in transferring it to the Wotan, the Wotan will have a 40" range 2/3 weapon against all vehicles. But it's point cost will be more in the 60 realm for the AR (Armor 5) variant. Still, worth it to me for a range 40" 2/3 vs armor, with a chance to reroll first hits. Potential (granted very lucky) chance to get 12 points damage on one attack. Easy to do sustained from 40" too. That Napalm throwers going to have to spend two-three rounds moving into range, while eating laser shots. More if it hides behind terrain to make it up. By then, I'm going to own my objectives.
Truthfully, I get what you say about laser-nerf from DT to DW. However, I thought it'd be horrible, but in actual play thus far for me, I haven't noticed them underperforming. Especially when I add Sigrid to a unit. However, I haven't tried the Herman, nor am I likely to, as LGs are better for 1 more point, and the Hans is easily the best 25 points I own, so the other two Axis lights are pretty hard to justify.
I just think the Wotan is going to do quite well.
